ROLLER SIDE BEARING.

SPECIFICATION forming part of Letters Patent No. 695,849, dated March18,1902.

Application filed November 8,1901. Serial. No. 81,584. (No model.)

To all whom it may concern:

Be it known that 1, JOHN C. l/VANDS, a citizen of the United States,residing at the city of St.-Louis, State of Missouri, have invented acertain new and useful Improvementin Roller Side Bearings, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is a plan view, partly inhorizontal section, of my improved roller side bearing. Fig. 2 is a sideelevational View, partly in section. Fig. 3 is a verticalcross-sectional view on line 3 3, Fig. 1; and Fig 4 is a sideelevational View.

This invention relates to a new and useful improvement in side bearingsdesigned particularly for use in connection with railway rolling-stock.The side bearing shown in the accompanying drawings is of that typeknown as roller side bearing, and in practice is arranged near the endsof a truck-bolster and on each side of the center plate or bearing, saidtruck-bolster side bearings cooperating with the side bearings arrangedon the bodytransom, which transom forms the support for one end of thecar-body.

The objects of this present invention are to simplify the constructionof roller side bearings and to provide resilient means whereby theantifriction device is returned to a normal or central position aftereach operation and independently of the movement of the top sidebearing.

My invention consists in the construction, arrangement, and combinationof the several parts, all as will hereinafter be described and afterwardpointed out in the claims.

In the drawings, 1 indicates what I will designate as the base-plate ofmyimproved side bearing, said base-plate carrying a track plate 2, whichtrack-plate is preferably made up of hard metal and removable, so as tobe renewed when worn.

3 indicates a wall rising from one side, preferably the outer, of thebase-plate, said wall having an overhang 4. 5 indicates a spring-housingrising from the opposite or inner side of the base-plate, said housingbeing formed with a slot 6, preferably, throughout its length, said slotopening inwardly, and said housing also having an overhang7 extendinginwardly from the lower edge of its top wall.

8 indicates a frame provided with sockets 9 in one wall and recesses 10in the opposite wall. ,These sockets and recesses are alined, so as toreceive spindles 11, which are journaled therein, said spindles carryingrollers 12. Rollers 12 overlap each other and are staggered and nested,as shown, being preferably loose on their respective spindles, wherebythey may rotate independently of each other. A plate 13 is secured tothe frame 8 to holdthe spindles in proper position in the recesses 1O.

14 indicates a web or fin extending from the frame 8, one portion ofsaid fin, as indicated at 15, projecting under the overhang 4, andanother portion of said fin, as indicated at 16, projecting under theoverhang 7.

17 indicates abutments projecting into the spring-housing'at each end ofthe fin 15. These abutments 17 are designed to operate through the slot6.

18 indicates spring-followers arranged in the spring-housing,betweenwhich is confined a coiled spring 19. A fixed stop or abutment 20 isarranged at one end of the springhousing, and a removable stop orabutment 21 is arranged at the opposite end of the spring-housing, withwhich abutments or stops are designed to cooperate the springfollowers.The inner walls of the abutments 17 in the normal position of the partsare substantially in the vertical plane of the inner faces of theabutments 20 and 21, as shown in Fig. 2.

In assembling the bearing the track-plate 2 is preferably riveted inposition. The frame 8, carrying the antifriction-rollers, is assembled,the rollers being strung on their respective spindles, and the spindlesinserted in the sockets 9, which, as shown in Fig. 3, are enlarged attheir bottom walls to permit of the tilting of the spindles and thesubsequent dropping of the spindles in position in the recesses 10. Theplate 13 is nowriveted in position. The antifriction-rollers beingassembled in the frame, the frame is now in readiness to be introducedinto position, and

to accomplish this the spring 19 is compressed between its followers andthe followers inserted between the projections 17. The stop 21 is ofcourse not in position and enables the roller-frame to be inserted atone side of the bearing, so that the spring and its followers will beproperly housed. After these parts are in position the stop 21 issecured in place.

It will be observed that the antifriction device is guided insuch mannerthat it will move on an arc of a circle described from the king-pin ofthe truck and that the independent rotation of the several rollers willpermit of this movement,the rollers rotating according to the arc oftheir path of movement as determined by the radius of that arc. Theliability of these sectional rollers to wear is thus reduced to aminimum and fiat faces are avoided because there is little inducementfor frictional contact.

The roller as an entirety can be assembled in the shop in readiness forapplication. The parts are easily assembled and dismantled, so thatrepairs and renewals may be quickly made. The base-plate and itsintegral walls are preferably made of malleable iron, while thetrack-plate is made of harder metal. The frame may also be made ofmalleable iron and the rollers of harder metal.

I am aware that many minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-
